LG has a new one that is really killer and I think there a group buy special going on.

Halltech(KillerB) and Vararam you will hear the most about.
Not wanting to be a smartazz, but if you hit the search button, in the red area at the top of this page, and type in 'cold air intakes' you can read for a couple of days about the subject.

I did the cut the shroud method with the Airaid unit, with the non oiled synthetic filter. Then added the "bee hive " cover to top it off. Works well. [ bee hive is from a different manufacturer , slight modification required ] .

I would try it out first to see how it runs!
It seems like you need to have your car tuned by a ($) professional ($) every time you do anything to your car. I think not! and this is my laymen reasoning.
1) Correct me if I am wrong but my understanding of the PCM/ECM is that it has the ability/programing to either lean or richen the air fuel ratio by as much as 25% in GM cars, other brands are over 30%. The reason for this is that less fuel would be required say on hot summer days and more fuel on cold winter days. Also these cars are sold just about everywhere with the same programing for the most part.
2) My own personal experience: I added "only" a CAI (my own design OEM "Home Made" CAI) and picked up 2 mph in the 1/4 mile and 3 tenths of a second from my best pure stock to my best CAI time.
I did not get a DIC light after the CAI install which means no trouble codes and the car ran fine/better.
Cooler/denser air from the outside will make more power than hot air from under the hood also the computer can pull timing/performance out of the engine when the measured air temp gets to 86 degrees and the underhood temp goes way beyond that a lot of the time which would pull even more timing out.

The PCM has the ability to trim +/- up to 25% in closed loop operation. This means when the PCM is reading the feedback of the O2's it has the ability to apply a Short term trim. These short terms will turn into Long term trims if the PCM is seeing this as a needed change. But lets say that the PCM is adding fuel in closed loop, that Long term trim will carry over to WOT but you have no idea what it is really doing and the PCM does not have any feedback on it. So it is better to calibrate it and be done.

Ok, you are right and wrong if that makes sense. As far as having to re calibrate it really depends on what you are bolting it onto and which one you are using. The LS3 could absolutely use a re-calibration for anything being bolted on.

You could add a Wide Band set-up like the Powerdex AFX air fuel monitor made by NGK Spark Plugs at a reasonable price to read your AFR to see where you are and also use it to do your own tuning if you have something like a DiabloSport Intune, etc.PS: If your car is running lean and it's out of the PCM adjustment capabilities then the DIC will throw a light/code from what I have read.

Positive LTFT's will carry over to the PE (power enrichment or WOT or open loop). The PE's values are programmed in the tune to deliver a specific A/F ratio at a given rpm. Additional fuel metering from positive LTFT's will richen those values in PE. This is why you will see maximum hp gains when a CAI install is followed by a tune.

I understand max power comes from an aftermarket tune after I install a CIA. The question was will the CIA alone cause engine damage?
If I drive in Denver on a 100 degree day, come over a 9000 ft pass, or drive at sea level in 40 degree temps. my computer has to adjust to those conditions. It seems logical that there is more A/F mixture change necessary there than adding a CIA. The car has to handle that.
Just my simple minded logic.

I have a Breathless Performanc CAI that I just took off my 08 LS3. This is a true CAI and is complete with the cut stock shroud. My car ran 10.9 with only bolt-on's and this CAI and 10.7 with a cam. I just removed it and installed a supercharger. I'll let it go cheap. I also have a spare filter element that goes along with it. I'll take $175 for everything..plus shipping, If your interested either PM me or call 561 654 4247. This set up works as well as the VaraRam without the problems of poor workmanship and possible water injestion. Thanks Mike

Sorry, but that much for an intake is absolutely ridiculous, especially when there are tons of intakes for the C6 that do the job only slightly worse or just as well.
